This repository provides an in-depth implementation of LZW compression and decompression algorithms for text files and images. It supports a wide array of formats and offers multiple compression ...

This is what run-length encoding requires. Correspondingly, delta encoding followed by Huffman and/or run-length encoding is a common strategy for compressing signals. LZW compression is named after ...

This project is a web-based visualization of the LZW (Lempel-Ziv-Welch) compression algorithm, designed to provide a clear understanding of how data compression occurs step-by-step. It includes ...

Abstract: This paper introduces an efficient data compression algorithm, which performs better then available LZW algorithm. Here, we propose a modified way to update the dictionary for LZW algorithm.

Abstract: In this work we propose a case of Hybrid compression i.e., Huffman based LZW. The performance of this algorithm is better than the traditional algorithm and it is observed to offer better ...

LZW compression is the compression of a file into a smaller file using a table-based lookup algorithm invented by Abraham Lempel, Jacob Ziv, and Terry Welch. Two commonly-used file formats in which ...

A lossless compression algorithm based on the LZW with compression ratios of 50 ? 60%, using 2K of RAM and 80% or more with 8K or 16K.

The GIF format uses the LZW compression algorithm, which was patented by Unisys, and publishers of applications that read and write GIF87a and GIF89a images were required to obtain a license and pay ...
